EGBERT R. MORRISON AND HORACE P. RODGERS, O15 CLEVELAND, OHIO,

COMBINED CHIMNEY AND ASH-PIT.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed March 27, 1920. Serial No. 369,406.

T 0 all whom it may concern.

Be it known that we, EGBERT E. MORRISON and HORACE P. Ronenns, citizens of the United States, residing at Cleveland, in the county 01' (Juyahoga and State of Ohio, have invented certain new and useful Improvements in Combined Chimneys and Ashlits, off which the following is a specification.

The object of the present invention is to provide a combined smokestack and ash pit, these devices being combined in a single structure which serves the purpose of both, and which will have certain advantages as more fully pointed out hereinafter. The structure may be conveniently built of concrete, and includes an ash pit located at the bottom of a chimney, into which pit ashes can be discharged by any suitable conveyer system and the chimney will take care of any dust arising therefrom.

The invention is illustrated in the accompanying drawing in which Figure 1 is an elevation of the structure. Fig. 2 is a vertical section thereof.

Ordinarily chimneys are built with a waste space at the bottom, and the ash pit constitutes a separate structure. In the present structure an ash pit is provided in the base of the chimney '7, below the breech ing opening 8. The bottom 9 of the ash pit may be elevated above the ground and provided with a gate valve 10 for the discharge or the ashes into a truck in the driveway 11 extending through the base of the structure.

The ash pit may be fully open at the top, to the chimney flue, so that dust and the like arising from the ashes will be carried up the flue and out at the top; and soot collecting in the flue may fall directly into the ash pit. Or, the ash. pit may be provided with a cover or top 12 at the bottom oi the flue, with a suitable vent 13 it necessary to let cit air and line dust. The ashes may be conveyed into th ash pit by any sort of an ash conveyer, such as a suction, forced draft or steam jet system, as known in the art.

We have shown a conveyer pipe ll which eX- tends through the side of the ash pit at the top thereof, and if a cover 12 is used said pipe will open through said cover into the pit below. A spout 15 may be tapped into the ash pit, to discharge ashes therefrom into a truck or car at the side.

it will be seen that little or no more ground room is required for both the stack and the ash pit than for the stack alone, the space below the breeching opening being utilized as the ash pit. Also, any dust arising from the ashes will be discharged with the smoke at the top of the stack instead of being distributed in the immediate vicinity of the pit. The soot is disposed of in a convenient manner. A cover over the ash pit is preferably used if the draft is so great, either in the flue or in the ash conveyer line, as to tend to carry an objectionable amount of dust or ashes up through the chimney, and any soot which falls 011 said cover may by a suitable opening in the wall just above the same be scraped so as to fall through the opening 13. The ash pit may be provided at the bottom with a drain pipe 16 to let 01? water of condensation when a steam jet is used.

We claim:

1. A chimney structure having an ash pit in the bottom thereof and a breeching opening into the chimney flue above said ash pit, and a conveyor pipe for ashes extending into the upper part of the ash pit.

2. A chimney structure having an ash pit in the bottom thereof, a cover between the ash pit and'the chimney line, said cover having a vent opening into the flue, and an ash conveyer pipe extending into the upper part 1 of the ash pit.

In testimony whereof, we athx our signatures in presence or" two witnesses.
